Help with setting-up home network

Hi, I have just had cat5e cabling put throughout my house. I have all of the cables terminating in one place in my study but I'm really struggling with the what's next part!
I have virgin media fibre optic input and I want wireless network as well as the hardwired rj45s that I have now set-up.
I think I need a patch panel in a network box but I don't know where to start. Can anyone help please?
